RESEARCH ON THE MOIRE CHROMATOGRAPHY TECHNIQUE AND ITS APPLICATION

Expound the Moire chromatography technique and the optical characteristics when the light crosses the air flow field. Based oil this. taking grating, CCD camera, optical filter and diaphragm etc as the main device. a multi-direction Moire chromatography optical system is designed. The system is consist of five detective light paths,, in each detective light paths there is parallel and same periodic grating, and filtering minipore placed on the lens focal length plane, the,rating is used to adjust the space length and included angle between the two grating: and the filtering, minipore is Used to remove the unorderly frequency intermixed in the Moire fringe. Utilize the computer escalator method to convert the tested Value. the vivid interference fringe of tested parameter call be obtained. In the end analyze and discuss the application of this system in precision measurement and medicine project,
